As a result of this con- In accordance with my presentinvention I 95 struction and mode of operation the cutting employ an integral or undivided die, whereedge of the punch is unprotected during the by the objections above noted are obviated setting of the eyelet, and if the eyelet is and the construction is simplified; and a feaslightly out of position or imperfect, as is freture of my invention consists in providing an 5o quently the case, it is forced against thc cuteyeleting oranalogous machine with a punch, loo

an integral setting-die, a cooperating die, and means for moving the setting-die into a position between its cooperating die and the punch.

In order to prevent the work being displaced during the setting operation, it is necessary that the setting-die be brought close to the surface of the work prior to the setting of the eyelet, and in order to allow the work to be fed it is necessary that the setting-die be out of contact with the work during its feeding movement. To these ends a feature of my invention consists in providing an eyeleting or analogous machine comprising a punch, a setting-die, and a coperating die with means for moving the settingvdie into a position between its cooperating die and the punch and for moving the setting-die toward the work. This feature of myinvention is notlimited to any particular construction of setting-die, although inv its preferred form the die is integral. As a means for supporting the setting-die during the setting operation I prefer to construct the punch so as to form an abutment for the setting-die when in a position between its coperating die and the punch, and I also prefer to actuate the punch to move the setting-die toward the work, and certain features of my invention consist in constructingand arrang-A ing the parts to so operate. As in the machine of the prior art above referred to and in the machine disclosedin my pending application,y

I prefer to employ the punch to feed the work, and certain features of my invention consist inproviding anA eyeleting-machine comprising a punch acting to feed the work with the devices andcombinations of devices hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

A machine embodying my present invention possesses the advantages of the machine disclosed in my pending application, in that the punch may he constructed to form a hole of any desired size in the Work regardless of the size of the eyelet., in that the setting-die is moved into a position between its coperating die and the punch, and thereby forms a protection for the cutting edge of the punchv to prevent the contact therewith of an eyelet or the eyelet-retaining spindle or'any portion of the cooperating die, and inthat the machine can be operated at a high rate of speed,`

since the setting-die can move into line with its coperating die as soon as the punch leaves the work. A machine embodying my present invention also possesses the additional advantages of being provided with an integral setting-die, whereby the eiiciency of the machine is increased and itsl construction simplified, and of being provided with means for moving the setting-die towardthe work, whereby any displacement of the work dur? ing the setting operation is avoided. Y l

y'A preferred form of my invention is illustrated in the accompanying drawings, in which- Figure 1 is a aviewin side elevation of an eyeleting-machine embodying the same, the mechanism for feeding the eyelets being omitted. Fig. 2 is a view in rear elevation of the machine shown in Fig. 1, a portion of the mav chine being broken away to show underlying parts. Fig. 3 is a detail plan view of the work-supporting table, the presser-foot, and the setting-die. Figs. 4, 5, 6, 7, and 8 are detail views, somewhat diagrammatic, illustrating the operation of the punch and dies in forming a hole in the work and setting an eyelet.

Referring to the drawings, 1 indicates the frame of the machine, and 2 a driving-shaft mounted in suitable bearingsin the lower portion thereof. To the shaft 2 are secured a driving-pulley 8, a cam-disk 4t, a block 5, and a crank-disk 6, from the three latter of which the moving parts of the machine are operated, as will be hereinafter described.

7 represents the lower setting-die, secured in the upper end of a rod 8, mounted to reciprocate vertically in suitable bearings at the front of the machine-frame. The rod 8 is reciprocated from the crank-disk 6 by means of a block 9, seated in a transverse slot in an enlargement of the rod 8 and loosely mounted upon the crank-pin 10. 11 designates a lever mounted upon a horizontal pivot at the upper end of a vertical shaft or rod 12, swivelingly mounted in the machine-frame. The lower end of the shaft 12 is provided with a nut 13, between which and the bearing for the shaft a strong spiral spring 14 is interposed. 'lhe rear end of the lever 1l extends through a slot in the yoke 15 at the upper end of a vertical rod 16, mounted to reciprocate in a bearing at the rear of the machine-frame.

YThe lower end of the rod 16 is provided with a roll 17, which engages a cam-groove 18, cut in the rear face of a cam-disk 4. The rod 16 is reciprocated by means of the cam-groove 18, and through the engagement of the rear end of lever 11 with the slot in the yoke 15 vertical oscillating movements are imparted to the lever. For swinging the lever 1l laterally with the shaft l2 as a pivot a lever 19 is pivoted upon a horizontal pivot 2O at one side of the machine-frame, the lower end of which is provided with a roll which engages a cam-groove cut in the front face of the disk 4, and the upper end of which extends into a position to bear against an adjustable stop-screw 2l,.pro jecting laterally from the rear end of lever 11. To hold the stop-screw 2l in contact with the upper end of the lever 19, a spiral spring 22 is provided, which connects the rear end of lever 11 with the lateral eXtension 23 of the upper end of lever 19. Screwing through one end of the yoke l5 is an adjustable stop-screw 24:, which limits the movement of the rear end of lever 11 in one direction. The spring 22 tends to hold the stop- IOO IIO

screw 21 in contact with the upper end of lever 19, but permits the lever to move away from the stop-screw when the lever 11 contacts with the adjustable stop 24. By adjusting the stop-screws 21 and 21 the extent of the lateral movements imparted to lever 11 may be varied as desired. The mechanism so far described, with the exception of the shape of the cam-groove 18, is the same as that of the well-known Hawkins eyeleting machine, such mechanism constituting suitable and efficient means for producing the desired movements of the lower setting-die and the punch. In the Hawkins machine the upper setting-die is mounted on the front end of the lever 11 and is actuated by the lever to enter the hole previously punched in the material by a separate punch and feed the material into a position to bring the hole directly over the lower die 7. In utilizing the mechanism of the Hawkins machine in carrying out my present invention I mount the punch in the front end of the lever 11, the punch being indicated at 25. The cam-groove 18 is shaped to impart to the punch 25 a downward movement to punch a hole in the material and thereafter to slightly raise the same to clear the worksupporting table without withdrawing it from the work. The cam 18 then acts to hold the punch 'so raised while the punch is moved by the action of the lever 19 on lever 11 to feed the work and bring the hole punched therein directly over the lower die 7. The cam 18 then acts to raise the punch and then depresses itslightly and holds it in this position during the setting operation for a purpose which will be hereinafter described. The cam-groove then acts to raise the punch, which is returned to its original position by the action of the lever 19 and spring 22 on lever 11. For supporting the work during the punching, feeding, and eyelet-setting operations a horizontal table 26 is provided, secured to the upper part of the front portion of the machine-frame. The punch, which is tubular, cuts against the surface of this table or against a cutting-block set therein, and the table is provided with an opening for the passage of the lower setting-die therethrough. An adjustable gage 27 is secured to the upper surface of the table in a position to engage the edge of the work as it is fed by the punch.

In the embodiment of my invention illustrated in the drawings the upper setting-die 28 is integral or undivided and is secured to or forms a part of the free end of an arm 29, projecting horizontally over the table 26 from a sleeve 30, loosely mounted upon the upper end of a vertical rod 31, rigidly clamped at one side of the front portion of the machineframe. Surrounding the rod 31 is a coiled spring 32, one end of which is secured to a collar 33, fast on the rod, and the other end of which is secured to the sleeve 30. This spring acts to swing the arm 29 to bring the setting-die 28 in line with the cooperating die 7, the movement of the arm under the teusion of the spring `being limited by a stop-pin 34, projecting downwardly from the sleeve 30, which contacts with a stop-pin 35, projecting upwardly from the collar 33. The collar 33 is adjustably secured to the rod 31 by means of a set-screw 36, whereby the position of the stop-pin 35 can be adjusted to bring the setting-die 28 in alineinent with its coperating die when the pins 34 and 35 are in Contact. When the die 28 is in alinement with its cooperating die, it is in the path of movement of the punch, and in order to allow the setting-die to be displaced during the feeding movement of the punch to bring the hole formed in the work directly over the die 7 the free end of arm 29 at one side of and above the setting-die is arranged to be engaged by the shank or enlarged portion of punch 25. The manner in which the arm 29 is moved during the feeding movement of the punch to displace the setting-die is indicated in Fig. 3, in which the arm is shown in full lines in the position which it assumes when the setting-die is in line with its coperating dieand in dotted lines in the position which it assumes when displaced by the punch. As the punch rises through the action of cam-groove 18, as described above, the arm 29 is actuated by spring 32 to return the setting-die to its original position in line with its coperating die, in which position it is between its coperating die and the punch. In order to allow the setting-die to move to this position as soon as the punch is raised from the work, a slot 37 isformed on the upper side of the arm 29 directly over the seting-die, into which the reduced portion of the punch passes as soon as the enlarged portion has been raised above the upper surface of the lever. In order to prevent the work from being displaced upwardly during the setting of the eyelet, it is necessary that the settingdie be in close proximity to the work during the setting operation. To allow the work to be fed, however, it is necessary that the setting-die be above the surface of the work during the feeding movement of the punch. To accomplish these results in the construction IOO lIO

shown in the drawings, the sleeve 30 is yieldoperation. The shoulder of the punch formed by the lower` end of the enlarged portion of the punch is accordingly utilized to form an abutment for the setting-die during the setting operation by bearing against the upper surface of the arm 29, the reduced portion of the punchbeing receivedin `the slot 37, as above described. After the punch 25 has been raised sufficiently to allow the settingdie to move toa position between its cooperating die and the punch the punch is lowered by the action of cam-groove 18, which has been described. This movement of the punch moves the setting-die into close proximity to the work,y and while the die is so held depressed by the punch the lower die 7 vis actuated to force auv eyelet through a hole in the work and set it against the setting-die.

For holding the work in position upon the table 26 the presser-foot 39 isprovided, secured to the upper end of a spring-pressed rod 40, mounted in suitable bearings in the machine-frame. A three-armed lever 41 (see Fig.. 1) is pivoted in lthe lower part of the machine-frame, one arm of which extends beneath the lower end of rod 40. The vertical arm of the lever 41 extends into a position to be engaged by a pin 42 on the block k5,which is secured to the shaft 2, whereby the lever 41 is actuated to raise the presser-foot from the work during the feeding movement of the punch. The third arm of lever 41 is connected, by means ofa rod or wire 43, to a treadle, (not shown,) whereby the lever 41 can be actuated to raise the presser-foot for the insertion and removal of work.

The operation of the machine above described will be clearly understood from an inspection of Figs. 4 to 8. Starting with the punch and setting-die in the position shown in Fig. 4,'the punch is actuated to form a hole in the work, the cutting edge of the punch coming in contact with the nppersurface of the feed-table 26 or asuitable cuttingblock set therein. The punch is then raised slightly to the position shown in Fig. 6 and then moved to the left, bringing the hole formed in the work directly over the lower die. During this movement the enlarged portion of the punch engages the arm 29 and moves it to one side, thereby displacing the setting-die, the parts assuming the position shown in Fig. 6. The punch is then raised to the position shown in Fig. '7, when the arm 29 is moved by the action of spring 32 to bring the setting-die into a position between its cooperating die and the punch. In this position the shoulder of the punch bears against the upper surface of the arm 29, and the reduced portion of the punch is received in the slot 37. The punch is then depressed to move the setting-die 28 in close proximity to the work, and the lower die is actuated to carry the eyelet retained thereon by the usual eyelet-retaining spindle through the hole in the material and set it against the settingdie, as shown in Fig. 8. The parts are then returned to their original position, and the cycle of operations is repeated. During the setting operation the cutting edge of the punch is protected by the interposition of the setting-die between its cooperating die and the punch, so that neither the eyelet-retaining spindle nor other portion of the lower die can come in contact therewith, nor can Van eyelet be forced against the cutting edge oi the punch.
